For CSV output, the filename has the format "apass_(RAdeg)_(DECdeg)_(radius).csv"

2012 May 30: For CSV output, the header line format has been changed to remove blank spaces and non-letter characters. Software that uses APASS CSV files as input may require modification.

Radius is currently limited to 15 degrees or less. If you need a larger query, or if you need data for a large list of individual stars, please contact us. Queries in rich star fields may take several minutes to complete.

APASS DR 8 and subsequent data releases are available on VizieR and the Virtual Observatory.
